Based on the data from field trial, new wheat varieties extension assisted by crop simulation model was studied. In this paper, six wheat varieties were also examined at five sites by using CERES-WHEAT model. After we inputting variety genetic parameter, soil parameter and weather data, CERES-WHEAT model was run to predict the phonological period, growth duration, yield and yield components of the six wheat varieties at five sites. Meanwhile the predicted values were compared with the measured values. Finally an integrated evaluation about variety ecological adaptation was conducted. The yield performance and ecological adaptation of a wheat variety can assist the decision in the course of the new variety extension. In addition, the author brought forward the application model of new wheat variety extension assisted by crop simulation model, which may be a new approach to cut down the cost and accelerate the new variety extension.
